NTPC Renewable Energy Limited (NTPC REL), a subsidiary of NTPC Green Energy Limited (NGEL), issued a Balance of System (BoS) tender on April 2, 2026, for a 200 MW grid-connected solar project in Bikaner, Rajasthan. This project is a segment of NTPC REL’s 1 GW Bikaner Solar Cluster, which was originally structured to include four blocks (two of 300 MW and two of 200 MW). The issuance of this new tender occurs alongside the recent finalization of contract awards for previous blocks, indicating a rolling procurement approach to complete the cluster’s total capacity.
Technical Scope and Project Requirements
The 200 MW BoS package includes the full development of project infrastructure. The selected bidder is responsible for the following scope of work:
- Design, engineering, manufacturing, supply, and installation of BoS components.
- Testing and commissioning of the project (excluding solar module supply).
- Foundation design and construction.
- Erection of tracker-based module mounting structures (MMS).
- Installation of PV modules on the MMS and module interconnection.
Specific specifications for the package are outlined in the table below:
NTPC REL 200 MW BoS Project Specifications
| Specification | Details |
| Capacity | 200 MWac |
| O&M Duration | 3 years from the date of full project commissioning |
| Inclusions | Electrical equipment, consumables, and spare parts for O&M |
| Exclusions | Supply of solar PV modules |
Project commissioning and final output are dependent on the separate procurement of ALMM-compliant modules, which the state-owned utility typically manages through independent tender cycles.

Strategic Context: Solarworld Award and Parallel Procurement
The launch of the April 2026 tender coincides with the issuance of a Letter of Award (LoA) to Solarworld Energy Solutions for Block-IX of the Bikaner cluster. Block-IX represents one of the 200 MW segments within the 1 GW development. This award follows a 12-month cycle originating from the April 2025 tender launch. By initiating new 2026 procurement rounds while simultaneously concluding 2025 awards, NTPC REL maintains an overlapping development schedule to manage the cluster’s infrastructure requirements.
The Solarworld contract specifics include:
- Project Block: Block-IX (200 MWac).
- Contract Value: Approximately ₹267.53 crore (including taxes).
- Timeline: Expected completion within 19 months.
This contract expands Solarworld’s regional footprint to 450 MWac of total capacity under contract with NTPC REL. The firm previously secured a 250 MWac EPC contract in the same region valued at ₹725.33 crore, which is scheduled for completion within the 2026–27 financial year. This recurring role highlights the vendor’s integration into NTPC REL’s multi-block development strategy in Rajasthan.
